Guidelines and HOWTOs/Build from source/Test plasma
Prepare the testing environment
Save the following script as /opt/kde/runPlasma5.sh
#!/bin/bash if [ -d /etc/X11/xinit/xinitrc.d ]; then for f in /etc/X11/xinit/xinitrc.d/*; do [ -x "$f" ] && . "$f" done unset f fi DISTRO=`source /etc/os-release 2>/dev/null; echo $ID_LIKE` export KF5=/opt/kde/install export QTDIR=/opt/qt5 # Change if you have your own qt build export PATH=$KF5/bin:$QTDIR/bin:$PATH export QT_PLUGIN_PATH=$KF5/lib/plugins:$KF5/lib64/plugins:$QTDIR/plugins:$QT_PLUGIN_PATH #On some distros, this is $KF5/lib64/qml:$QTDIR/qml or something similar. After the installation, choose the directory/directories which contains the "qt/qml" folder. export QML2_IMPORT_PATH=$KF5/lib/qml:$QTDIR/qml #Fixes for Debian's "look at me, I'm so important" setups if [ $DISTRO == "debian" ] then export QT_PLUGIN_PATH=$KF5/lib/`uname -m`-linux-gnu/plugins:$QTDIR/plugins export QML2_IMPORT_PATH=$KF5/lib/`uname -m`-linux-gnu/qml:$QTDIR/qml fi export QML_IMPORT_PATH=$QML2_IMPORT_PATH export XDG_DATA_DIRS=$KF5/share:/usr/share export XDG_CONFIG_DIRS=$KF5/etc/xdg:/etc/xdg # Uncomment to change default home paths #export XDG_DATA_HOME=$HOME/.kde5/local #export XDG_CONFIG_HOME=$HOME/.kde5/config #export XDG_CACHE_HOME=$HOME/.kde5/cache exec startkde
For what works on Debian Sid alongside with packaged KF5 nicely see: Using (parts of) self-built KF 5, Plasma 5 and/or KDE Applications on Debian
Because we installed Plasma 5 to a custom path, we need to make dbus aware of these new locations.
Create a file /etc/dbus-1/session-local.conf with the following contents:
<!DOCTYPE busconfig PUBLIC "-//freedesktop//DTD D-Bus Bus Configuration 1.0//EN" "http://www.freedesktop.org/standards/dbus/1.0/busconfig.dtd"> <busconfig> <servicedir>/opt/kde/install/share/dbus-1/services</servicedir> </busconfig>
Create another file /etc/dbus-1/system-local.conf with the following contents:
<!DOCTYPE busconfig PUBLIC "-//freedesktop//DTD D-Bus Bus Configuration 1.0//EN" "http://www.freedesktop.org/standards/dbus/1.0/busconfig.dtd"> <busconfig> <servicedir>/opt/kde/install/share/dbus-1/system-services</servicedir> <includedir>/opt/kde/install/etc/dbus-1/system.d</includedir> </busconfig>
Because dbus will load all these new paths each time you login, you should rename these files (to eg system-local.conf.bk and session-local.conf.bk) before starting your default Plasma 4 or other distro sessions.
Finally, there are several ways of running Plasma 5. Choose the one which suits you best.
Using a login manager
The recommended login manager is SDDM. But this method should work with any login manager.
sudo cp /opt/kde/runPlasma5.sh /usr/share/xsessions sudo chmod +x /usr/share/xsessions/runPlasma5.sh sudo cp /opt/kde/install/share/xsessions/plasma.desktop /usr/share/xsessions/plasmaGit.desktop
Edit /usr/share/xsessions/plasmaGit.desktop and change the paths as:
Exec=/usr/share/xsessions/runPlasma5.sh TryExec=/usr/share/xsessions/runPlasma5.sh Name=Plasma Git
After this logout of your current session, select Plasma Git in the options and login. You should now have the last Plasma 5 running.
This is what I found works on Debian Sid nicely. Put the script which sets up the environment into ~/.config/plasma-workspace/env, chmod +x it and be done. Aside from the "Using a login manager" approach probably – I didn´t test it –, this is the only thing that worked on Debian. Additionally to that it does not need any changes to system wide configuration files. This directory replaced ~/.kde/env from KDE SC 4 and older times.
Specifically none of the put it into some user wide or system wide shell profile files worked. Also putting it at start of /usr/bin/startkde worked, as environment still got reset to the default.
From the command line
Edit your xinitrc file:
mv ~/.xinitrc ~/.xinitrc.bk # Backup any existing xinitrc file ln -s /opt/kde/runPlasma5.sh ~/.xinitrc
Log out of your current session, login to a tty (eg tty2 by pressing
Ctrl+Alt+F2) and run
startx. This should read your ~/.xinitrc and log you into a Plasma 5 desktop.
